TQC Hardness Test Pen
Determination of Scratch Resistance of Paints & Varnishes
The TQC Hardness Pen is a pocket instrument for testing the hardness and wear/scratch resistance of materials such as coatings, lacquers, plastics or related products.
A tungsten carbide tip is drawn over the surface with a defined constant pressure. The pressure on the tip can be changed using the slide or by changing the spring. A visual mark on the surface after use of the TQC Hardness Pen indicates a fail of the surface hardness or wear/scratch resistance. Can be used on flat and curved surfaces. The laser-engraved scale is clearly visible on the grey background.
There are 2 versions available, the Standard and Pro.
The Standard version is supplied with 3 springs and one tip:
Blank spring: 0-3N, graduation 10 g
